Charlie Peprah had an expanding role this year after Nick Collins' season was cut short after a neck injury.
He had a decent year with five interceptions and 94 tackles. If Collins is unable to return to football because of his injury, the Packers will want someone else at safety other than Peprah. The team has already considered moving Charles Woodson from cornerback to safety to fill in for Collins if he is not cleared to play.
Collins will let the team know before the draft if he can play football next season. If he is not ready to play, the Packers will need to dump Peprah and improve at the safety position, which in turn helps the cornerback spot by keeping Woodson there.
If the Packers want to move Woodson to safety, knowing how valuable he is as a cornerback, it shows the lack of faith they have in Peprah. Unlike Collins, he lacks the ability to be a difference maker and is an easy target for quarterbacks.
